At least 80 airdrops were made by the Charlotte County Sheriff's Office's aviation unit, it said in a Facebook post.

The forestry service deemed the blaze contained by 10:30 a.m. Saturday, nearly 18 hours after it began, Avni said.

The brush surrounding the overflow area caught fire and help its quick spread, but no structures at the airport were affected, Avni said. No injuries were reported and the cause of the fire is under investigation, she said.

In a Facebook post, the airport thanked all the agencies who responded to the blaze.

"We appreciate their courage and willingness to help our Aircraft Rescue & Fire Fighting department. Together they were able to keep all our passengers and airport visitors safe," the airport said.
